Returns a value indicating whether the given point is within the boundary of the geometry. The hit test results are also returned.
public:
override bool DoHitTest(Microsoft::VisualStudio::Modeling::Diagrams::IGeometryHost ^ geometryHost, Microsoft::VisualStudio::Modeling::Diagrams::PointD hitPoint, Microsoft::VisualStudio::Modeling::Diagrams::DiagramHitTestInfo ^ hitTestInfo, bool includeTolerance);
public override bool DoHitTest (Microsoft.VisualStudio.Modeling.Diagrams.IGeometryHost geometryHost, Microsoft.VisualStudio.Modeling.Diagrams.PointD hitPoint, Microsoft.VisualStudio.Modeling.Diagrams.DiagramHitTestInfo hitTestInfo, bool includeTolerance);
override this.DoHitTest : Microsoft.VisualStudio.Modeling.Diagrams.IGeometryHost * Microsoft.VisualStudio.Modeling.Diagrams.PointD * Microsoft.VisualStudio.Modeling.Diagrams.DiagramHitTestInfo * bool -> bool
Public Overrides Function DoHitTest (geometryHost As IGeometryHost, hitPoint As PointD, hitTestInfo As DiagramHitTestInfo, includeTolerance As Boolean) As Boolean
Parameters
- geometryHost
- IGeometryHost
The instance data for the geometry.
- hitPoint
- PointD
The point to test. The point is in world units and is relative to the top-left of the IGeometryHost's parent.
- hitTestInfo
- DiagramHitTestInfo
The object which will be updated with the hit test results.
- includeTolerance
- Boolean
true to include tolerance in the HitTest calculation; false to exclude tolerance.
Returns
true if the given point is within the boundary of the geometry.
Remarks
The geometry boundary includes the thickness of the outline pen that lies outside of the graphics path used to draw the geometry.
